Dimebug Plans - Help

Hi All,

 

I'm working on the left and right consoles from Dimebug's plans, but I've hit a snag.

 

I have 16mm Square aluminium tubing that I'm using for the DZUS rails, but I cant figure out how to stick the corners together. I've mitred the edges and they have a clean, close fit but anything I do to join them is too weak.

 

I spent the weekend smearing it all in a ton of epoxy, gave it 2 days to cure and came in now to examine my handy work; which disintegrated when I picked it up :(

 

What technique is everyone else using? Any pointers appreciated.

 

Jim

Hi Deadman,

 

As always, thanks for the quick reply.

 

This is the frame i'm trying to put together (pls excuse the crew chief :lol:):

You can see the mitred corners here (i'm not 100% this is the right thing to do):

Any pointers much appreciated.

I'm not sure I can name one product where designers and engineers decided to use epoxy for connecting aluminum. Take it from pros, if welding is not an option use screws . Or at least rivets.

 

If you insist on gluing it increase contact surface (with side braces perhaps ) and get in a habit of not breathing that much when near it :)

well several thing are going wrong here, first your just using epoxy on dirty aluminum (the wrong type of adhesive) on the edge of the square tubing, not enough surface area for proper adhesion. I would suggest you use Extreme 310 from http://www.extremeadhesives.com/acrylics.php

and use a flat bottom plat cut from possibly 6061 aluminum 1/8 inch thick cut as a L and places on the bottom of the corner.

The following post give a get over view and some guidance on using adhesives on aluminum http://www.homebuiltairplanes.com/forums/aircraft-design-aerodynamics-new-technology/5293-conclusions-aluminum-adhesive-bonding-tests.html

Here is a vidio of a test on the adhesive

CNCs and Laser engravers are great but they can't do squat with out a precise set of plans.

Hi Mike i have used it on several non cockpit related projects where the heat from wielding the aluminum would possibly warp or distort the project out of spec with a properly cleaned material it bonds better and faster:thumbup: than other adhesives i have tried it will be used in some places on my project.
